I am trying to find out if I can link these symptoms with anxiety disorder.

I started to have random night sweats, like once a week maybe. I don't sweat a lot, just a bit and only near my neck and arms. I don't have soaking wet clothes when I wake up.
What about leg weakness? or leg joint weakness?
Can it be from anxiety/stress...to much thoughts about my health?

Before I was not worried about everything about my health but now I am scared about all things that are new or unnoticed before.

I suffered with anxiety and panic disorder years ago which I have now learned to control without medication. First of all, it's amazing what the mind can do to your body. I used to get symptoms of all sorts when I focused too much on being worried about acquiring a life threatening illness (believe me there was a lot I swore I "had", from brain tumors to you name it). And it would suddenly seem as though I had all the symptoms that were described for any type of disease I was worried about at the time.Of course, this was not the case and I was fine.

However, if you do have a history of any professionally diagnosed illness that may cause your symptoms, or they do become worse, get it checked out.

In the meantime find ways to relax and assure yourself that you are fine, because you probably are.

Sometimes, when I am in different situation I get scared and then I start to feel that I lose control over my body...
Also sometimes when I am in traffic and it's crowded I get some strange feelings...I feel like running away in a safe place, without nobody...without cars...it's weird!
I had the same problems as yours, I am quite often thinking about all the worse diseases, from brain tumor to all types of cancers...
Now I started not to look anymore so much on the internet...

Control is a big thing with anxiety disorders. A huge reason why I always got anxious and then panicked was because I felt a lack of control in general; over myself, over disease and all the other bad things that COULD happen to me, I was afraid of a lot of things.

There is no need to be afraid of all that. I could tell you that all of this is "in your head" but I know it seems more than that. I hated it when I would be told that, because the person telling me obviously didn't understand how difficult it was, it was a half *** answer to the problem.

Being active is one of the best things. Go running regularly, lift weights, get some aggression out. The more confident you feel, the more these little fears start to diminish. Also avoid all caffeine, energy drinks and sugary drinks (including soda). Be around good people as much as possible. Prioritize your work so you aren't stressed at all.

I find that the control issue has alot to do with fear and anxiety. Thats why I have it. I can't surrender control very easily. It's hard for me to let anyone else to be in control, like flying the plane, being the doctor and giving me meds, and that gives me fear of flying and fear of diseases and pills. I don't know if that makes sense.
